Reply To: Can't get MAX2Play on Raspberry Pi 0/W with HifiBerry Amp 2 to work

Hi Barry,

Glad to hear you got it working.

The issue is actually not undervoltage but inexperience with such high levels of voltage on the zero. Other issues are the lower computing power, which can get problematic mostly with Squeezebox Server installed, and the dimensions of the Pi. The AMP2 was designed and developed with the standard HAT dimensions of the main Pi’s in mind. Those are Pi 2B, 3B, 3B+ or 4B. All these are the primary devices for use with Max2Play and the ones we are testing it on continually. The Zero Wireless is a nifty smaller option for smaller setups e.g. just running Squeezelite. There are also specific sound cards for the zero Pi’s like MiniAmp or DAC+ Zero.
